To all whom it ma concern:

Be it known that Wlmmr LYON, a citizen of the United States, residi fordsville, in the county of ontgomery I, and State of Indiana, have invented certain new and useful Improvements in Timer Brushes; and I do declare-the followingto be a full, clear,v and exact description of the vinvention, such as will enable others skilled at Crew- 10 in the art to which it appertains-to malceand usethe same. h

This invention, relates-to improvements in timer brushes, the same being particularly designed for use in connection with Ford 1&- machines, although it is not to be restricted to such use.

The principal object of the invention is to produce a device of the above mentioned type which will overcome, as much as 'possible, excessive wear on the contacts and insulation of thetimer shell, but at the same time will make .a firm wiping contact at all times.

A further object of the invention is w I 25 provide means associated with the shoe and contact brush to lubricate the path of travel of the shoe and brush, said shoe also having means associated therewith to collect. any

surplus dirt and oil. r

Another object of the invention is to rovide a device of the type specified-whic is 7 simple in construction, strong, durable, ef-

fective imoperetion, and comparatively nexpensive to manufacture. u

the entirecircum .in whichit operates. Because of the peof good wearing quality, and is substantially semicircular 1n configuration, its size being equal to approximately one-half of erence of the timer shell culiar shape and size of this shoe 6, it will be seen that it will fit snugly in the shell, thus serving as a substantial relative bracing means for the shell and timer shaft, and at the same time insuring a perfect wiping contact at all'times and preventing excessive vwear on the contact points and path of the timer shell. Notches 7 are provided in the inner edge of the shoe and these notches fit loosely over the guide or hearing pins'5 in the carrier, thus rmitting the shoe to move freely in a ra ial di rection with respect to the carrier and at the same time causing rotation of the shoe with the carrier. This construction also permits the shoe to be reversed whenever desired. Such reversal of the shoe will be found advantageous in that it will compensate wear. It also serves another The brush block 6 is recessed at 8 to permit the armsv4 of the carrierto fit thereini The to shoe is provided at its center with a radial'opening llin which a gauze contact brush 9'is seated and normall pressed out against the contact points in t e timer shell by a'coil s ring '10 which bears on the carrier 1, said sprmg bein held in its proper position by an outward y on the carrier 1. g Y To prevent dirt and ummy oils from collecting on the path-of brush 9 and interfering with the proper operation there of, I provide transverse notches or gutters 13 in thebearing surface of the shoe which serve to collect an dirt and oil, thereby protecting the brus The notches are, by preference, located on opposite sides and close to the brush. =9, or rather, the opening 11.
